a is the base from which rises vertically a standard a? which curves at its upper end to a horizontal position forming a goose neck a a is a short projection in the standard a which also rises. from thebase a. 0 indicates a way at the side of the standard a 0 is a movable supporting 'piece adapted to travel on the way 0 and balanced by a weight 0 with which it is-connectedby a chain c passing over a'pu'lley 0 There is a'crank c by which the pulley '0 may be rotated. to adjust thepositionofthe supporting piece'c. c isa pitman, or'sliding rod,:pivoted at its upper end to the supporting piece a beneath the work receiving portion ofsaid supporting piece and extending vertically downward into an .aperture in the projection a The rod, or ;pitman, c is provided with transverse holes 0 and a corresponding hole is formed through the walls of the aperture in which saidrod-or pitman reciprocates. The table 0 is .adjustedto the desired position and a pin is inserted through that one of the holes 10* which registers with the holes in the wall of said aperture.

cl representsa wheel through which power is imparted to the machine .by means-ofa belt or otherwise. upon-ashaftd (Fig. 2) whichiss'upport'ed in a rigid bea'ringd 'in-a bracket a -secured to the standard a and extending laterally and upwardly'therefrom. d is-a pinion on the inner-endof the shaft 8Z 7?. is a hollow spindle supported to rotate on the frame'of the machine. The left hand end of the spindle h is jointed to a stub spindle 1' which has a pinion 1' at its left hand end. The stub spindle 'r' rests ina bearing 8 at the outer endof the go0seneck-a b is a 'bar adapted to reciprocate vertically in a bearing at the outer end of :the goose-neck and=being provided with-a rack b ,(Fig. 4). t is an arbor having agear wheel t at its inner end and a hand-wheel't at itsouter end. .The pinion-1" engagesthegearwheel t. t is a pinion 'rigidlyconneeted with the gear wheel t concentric thereto, its teeth engagingv the rack teeth b on the recipror eating bar I). 7

It will be seen that by rotatingthe spindle h and stub spindle r the barb may 'be moved by means ofthe pinion r gear wheel 25, pinion zi -and rack 6 or iftheiparts are otherwise free to move, the bar '6 maybe adjusted to any desired vertical position-by rotating the wheel 't 'byliand.

c is a gear wheel having internal gear The wheel 03 is :mounted teeth 6 and a hub c fitting and adapted to turn upon the spindle h. e is a conical annular flange secured to the wheel e concentric therewith and extending from the web of said wheel.

p is an annulus sleeved upon the spindle it and secured thereto by a key, or feather, p which permits of a motion of the annulus longitudinally of the spindle but restrains relative angular movement. 12* is a cylindrical portion of the annulus 29 extending over the flange e on the internal gear wheel a and having its internal face shaped to, and adjacent, or contiguous, to the exterior surface of said flange. g is a clutch piece adapted to be engaged with and disengaged from the interior surface of the flange a g indicates lugs which extend from the clutch piece 9 through apertures in the annulus p so that there may be relative motion of said clutch piece and annulus axially of the spindle h but no relative angular movement. There are bell crank levers pivoted at g to lugs extending from the clutch member 9 and having outwardly extending arms Q6 which bear, through an adjustable screw upon the vertical face of the part 79 of the annulus p.

There is a sleeve m adapted to slide upon the spindle h longitudinally thereof and provided with a groove m and a conical cam surface m. The bell crank levers pivoted to the lug of the clutch piece 9 have arms 9'' extending to the exterior surface of the sleeve m and adapted to engage the cam surface m thereon.

The internal gear wheel 6 is adapted to turn freely upon the spindle h except when clamped thereto by the mechanism just above described. By moving the sleeve m toward the left the cam surface on actuates the bell crank levers to draw the clutch piece 9 into engaging position against the flange e which binds the wheel 6 to the annulus p and thus to the spindle h. The motion of the wheel 03 and shaft d will then be imparted to the wheel 6 through the pinion d (Fig. 6) and internal gear teeth 6 so as to give a slow downward movement to the bar I) at a very powerful leverage.

There is a gear wheel sleeved and adapted to turn upon the spindle h and having exterior gear teeth and an outwardly flaring internal conical clutch surface. The pinion d is geared to the pinion 7 through an intermediate gear Wheel d (Fig. 6) so that the motion of said pinion is imparted to the wheel 7.

There is a gear wheel 9 similar to the gear wheel f and having a face adjacent thereto. The gear wheel 9 has exterior gear teeth and an outwardly flaring internal clutch surface. The wheel 9 is also sleeved upon the spindle h and adapted to turn thereon. (i (Fig. 6) is a gear wheel, the teeth of which gear directly with the internal gear teeth 0 and exterior gear teeth of the wheel g. The motion of the pinion d is communicated to the interior gear wheel a and from that through the gear wheel d to the gear wheel 9.

It will be observed that the direction of rotation of the wheel 9 is opposite to that of the wheel f.

f is a clutch part adapted to engage and be disengaged from the interior surface of the wheel 7, and g is a similar clutch part adapted to cooperate with the internal surface of the gear wheel g. There are bolts f extending from the clutch part f through apertures in the clutch part and having springs g threaded thereon adapted to yield ingly hold the clutch parts f g with their inner faces contiguous.

The clutch parts f and g are adapted to slide longitudinally upon the spindle h but are restrained from angular motion relative thereto.

When the clutch part f engages the wheel 7 a rapid downward motion will be imparted to the bar I). When the clutch g engages the'gear wheel 9 the gear wheel f will be re leased and a rapid upward motion will be imparted to the spindle h.

There is a sleeve j (Fig. 11) fitting and adapted to reciprocate within the spindle h. The sleeve on is rigidly secured to the left hand end of the sleeve j by a pin m which is fixed in said sleeve at its ends, passes through slots h in the spindle h and is fixed in the walls of the sleeve j.

There is a pin 9* fixed in the clutch piece g extending through slots k in the wall of the spindle h and through slots j in the wall of the sleeve j.

In the normal position of the parts the pin 9 engages the walls of the slots j at the left hand end of said slots. If the sleeve 17?, is moved toward the right, as shown in the figures, the sleeve y will act on the pin 9 tomove the clutch piece 9 into engagement with the gear wheel 9 so as to b. If the sleeve m is moved to the left it will disengage the pin 9 permitting the dis engagement of the clutch part 9 A further movement to the left of the sleeve m will leave the pin free because of the relative position of the slots j and will cause the engagement of the gear Wheel 6 withthe spindle h as above described.

It is a rod fitting within the sleeve 7' and adapted to reciprocate therein. The right hand end of the rod his connected by a pin f passing freely through slots in the sleeve j and spindle h, with the clutch part F. A movement of the rod is toward the left will move the clutch part f into engagement with the wheel 7 thus binding the Wheel to the spindle k and causing the fast downward movement of the bar 6.

cause the fast upward movement of the bar to (Figs. 2 and 9) is an arbor or rock-shaft pivoted in bearings in the frame of the machine and extending in a direction at right angles to that of the spindle h beneath the groove m 'in the sleeve m. The arbor 'u is provided with yokes a which extend upwardly therefrom and engage by means of the usual cylindrical pins in the groove m on the sleeve m.

By rotating the arbor a to the right the sleeve m is moved in that direction to engage the clutch part g with the gear wheel 9; by rotating said arbor in the'opposite direction the sleeve on is moved to the left to cause the engagement of the clutch part 9 binding the wheel 6 to the spindle h.

Upon the arbor 'u there is a grooved sleeve 2 (Fig. 3) adapted to reciprocate on said arbor; and within an axial opening in the arbor u, there is a rod 10' adapted to fit and reciprocate longitudinally therein. There is aspring a (Fig. 9') acting to press the rod 10* to the outer limit of its travel.

There is a pin 3 extending through slots in the walls :of the arbor 'w and engaging the sleeve 2 with the :rod 14*.

w (Fig.3) is a bell crank lever pivoted upon a vertical pivot and having an arm 00 extending and engaging in the-groove of the sleeve 2, and an arm .00 extending under the sleeve a and engaging by'a pin in the groove of said sleeve.

There is a crank piece a secured to the outer end of the arbor "w and provided with a radially extending groove opening outward. Within the'groove in the crank piece a is pivoted at v a lever arm 2;. The rod 10 extends at its outer end into the groove in the crank piece a and may be engaged by the inner edge of the lever arm o. 7 By raising the lever arm 0 up or down the crank piece a is actuated to oscillate the arbor There is a quad-rant flange a" formed upon the :casing of the machine over which quadrant the lever arm o'travels. The quadrantw isprovided with anotch Z02 (Fig. 10) the lower wall 20 of which slants outwardly. When the lever arm 12 comes opposite the notch or groove w' it maybe turned inward about its pivot 4) thus actuating the reciprocating rod a the sleeve 2, the bell crank lever 00, forcing the sleeve it toward the left and drawing the clutch piece 7 into engagement with the gear wheel 5 f to the spindle '72, and causing the fast downward movement of the bar I).

The operation of the above described device is as follows:

The work is placed upon the bed plate at the upper surface of the supporting piece a and said piece is adjusted by means of the crank 0 to a convenient position and fixed therein by inserting a locking pin through one of the holes 0 The handle o is then moved into the slot to in the quad- The lever scribed, thus forcing the arbor into posi tion.

raising the lever arm 41 to its normal or approximately horizontal position, the power is disengaged and the bar 1) comes to rest. By raising the lever arm '0 upward, the sleeve on is moved toward the right thus moving the clutch piece 9 by means of the sleeve j'into engagement "with the gear wheel g so as to secure the fast downward movement of the bar b. When the bar is sufiiciently raised to leave room for'the withdrawal of the work the lever arm o is moved backward to its normal position opposite the slot or notch 10 in itlle quadrant "w and the parts are disengaged tion the bar 6 may be adjusted to any position by the hand wheel It will be noted that the movements of the lever :are in the natural directions. For instance, if the operator desires to raise the bar b he raises the lever arm, having adjusted the work "to position and wishing to bring the bar t down into the neighborhood of the work without actually operating upon it, which is an unusual and auxiliary operation, he moves the lever arm laterally. Having .got the bar '2) into position to begin its forcible operation by the slow movement downward at a considerable leverage he merely presses the lever arm 'down'in the direction he wishes the bar to go, the slanting edge of the slot in the quadrant w moving the lever laterally'out of the slot.
